Does anybody know where I can get map of the LEXUS V8 ECU. I am looking for addresses of fuel-ratio map and Transmission map in the ECU. I want to access those locations using OBDII.

I read that car manufacturers promised to release their OBD-II information in september of last year, but I haven't seen it yet.

I know that it is proprietary information, but maybe someone can point me to the right place!

 

I have been looking for the same thing, access to the data and its location.

Have you made any progress
